info: inspirational links from slack

@Sharpie wrote in the slack:

https://observablehq.com/@d3/gallery is also a good source of inspiration.

In particular, this looks like it could be a good solution for the "multiple inheritance" problem that the contain() function can create: https://observablehq.com/@nitaku/tangled-tree-visualization-ii

The TensorBoard graph is also worth looking into, as it has to deal with the high complexity of machine learning models --- which is a problem that pops up with large puppet catalogs: http://idl.cs.washington.edu/files/2018-TensorFlowGraph-VAST.pdf

The PE Node Graph was built from scratch by one of the engineering teams and did not use the above prototype, but it did build on top of this open source library: https://github.com/dagrejs/dagre-d3
